What steps will reproduce the problem?

2.querying the database
3. attempting to write to database

What is the expected output? What do you see instead?

I expect to see 2 strings added to the database instead I get console errors. .
[ERROR] could not pass event TransactionEvent to ChestShopDB v 1.0

What version of the product are you using?
Craft-Bukkit 1.8.7
ChestShop 3.8.10

Do you have an error log of what happened?
Caused by: java.lang.RuntimeException: java.lang.RuntimeException: java.sql.SQLException: query does not return results

Please provide any additional information below.

Ok I know this is an old file. . .but I am trying to utilize this on a server that I am working on creating.  I am only interested in logging unique transactions to the .db file.  However I am having a lot of difficulty (I believe) getting the connection to the database, checking the contents, and writing the new items. .

I have narrowed it down to be an issue something with the accessing of the database.
I can retrieve the desired data from the TransactionEvent such as event.getOwner() and event.getClient().getName(),  event.getSign().getLine(0).

ChestShop v 3.8.10
